Headquarters, Washington, D.C.          July 27, 1993


    NASA today announced the assignment of Dr. John Cox as acting Deputy
Director, Program and Operations, Space Station Freedom Program, and Robert
Moorehead as Chief Engineer for the Office of Space Systems Development (OSSD),
NASA Headquarters, Washington, D.C.

    The announcement was made jointly by Arnold D. Aldrich, Associate
Administrator for Space Systems Development and Space Station Transition
Director Bryan O'Connor.

    Cox currently serves as Deputy Manager for Operations, Space Station
Freedom Program. He was named to the Station Redesign Team in March and played
a key role in the development of the operations concept for the redesigned

7/20/93:  LAUNCH ADVISORY:  JULY 24 NEW DATE FOR STS-51 LAUNCH

     NASA managers today set July 24 as the new launch date for Shuttle Mission
STS-51. The launch window on July 24 opens at 9:27 a.m.  EDT and extends for 54
minutes.

     The decision to go with July 24 as the new launch date follows the
completion of work to inspect and retest the Pyro Initiator Controller (PIC)
unit on the launch pad.  A problem with the unit caused the Kennedy Space
Center launch director to call a scrub during a launch attempt on July 17.

     "The July 24 date is the best date all around for the launch of Discovery
on the STS-51 mission" said Shuttle Director Tom Utsman. It gives enough time
for KSC technicians to complete work on the PIC unit, the payload community
time to service the STS-51 experiments and the entire launch team enough time
to put the Shuttle system back into launch configuration.  The July 24 date
also is one that the Air Force range safety community can support."

     Shuttle Mission STS-51 will see Discovery's five person crew deploy the
Advanced Communciations Technology Satellite which will give industry, academic
and government organizations an opportunity to investigate new ways of
communicating.  The crew will also deploy and retrieve the Orbiting and
Retrieveable Far and Extreme Ultraviolet Spectrometer (ORFEUS- SPAS).

NOTE TO EDITORS:  N93-38

    Following today's STS-51 Flight Readiness Review at NASA's Kennedy
Space Center, Fla., mission managers targeted July 17 at 9:22 a.m.  EDT for
launch of the Space Shuttle Discovery on its 17th flight.

    Primary payload activity on the 9-day mission will include deployment
of an Advanced Communications Technology Satellite (ACTS), and deployment and
retrieval of the German- built ORFEUS-SPAS astrophysics free-flier.  A 6-hour
Extra Vehicular Activity, or space walk, will also be performed by two
astronauts.

    Commanding the STS-51 crew is Frank Culbertson who will be making his
second space flight.  Pilot Bill Readdy has also flown once in space.  Three
mission specialists, each flying for the first time, round out the 5-man crew:
Jim Newman, Dan Bursch and Carl Walz.

7/27/93: STS-51 NEW LAUNCH DATE SET / Launch Delay Information


    Launch of Discovery on mission STS-51 has been rescheduled for
Wednesday, August 4.  The launch window is yet to be determined and will be
clarified later today.  The countdown is scheduled to pick-up at 9:30 a.m. on
Sunday, August 1 at the T-43 hour mark.

     Work at the pad to remove and replace the right hand solid rocket
booster's (SRB) Auxiliary Power Unit (APU) continues today.



STS-51  ACTS-TOS/ORFEUS-SPAS

      The launch of Discovery on mission STS-51 was halted last Saturday at the
T-19 second mark due to a problem with the Hydraulic Power Unit (HPU) on the
right hand Solid Rocket Booster. The HPU controls the rock and tilt actuators
on the booster's nozzel.  Specifically, the problem was narrowed down to the
Auxiliary Power Unit (APU) which is the power supply of the HPU. This resulted
in a lower than allowable turbine speed.  As a result, only the APU will be
replaced.  The faulty unit will be returned to the vendor for complete failure
analysis and a new unit will be installed later this week.  No additional work
is scheduled for the left hand booster.

     Early assessments indicate another launch attempt will occur no earlier
than Monday, August 2.  To support this effort, a com- plete countdown will be
required and the clock recycled to the T-43 hour mark.


PREVIOUSLY ISSUED LAUNCH DELAY INFORMATION FOLLOWS


KENNEDY SPACE CENTER SPACE SHUTTLE STATUS REPORT
Tuesday, July 20, 1993

      An announcement is expected later today from NASA managers giving a firm
launch date for Discovery on mission STS-51. At this time, launch will not
occur before Friday, July 23.

     The problem circuit card in the pyrotechnic initiator controller which
caused the launch scrub on Saturday has been replaced on the mobile launcher
platform.  Efforts to duplicate the problem on the suspect card were successful
at KSC's malfunction laboratory.  A thermally unstable circuit was the culprit.




KENNEDY SPACE CENTER SPACE SHUTTLE STATUS REPORT
Monday, July 19, 1993

MISSION: STS-51  ACTS-TOS/ORFEUS-SPAS

      Launch of the space shuttle Discovery on mission STS-51 was scrubbed
Saturday at the T-20 minute mark due to a problem with a switch in the
pyrotechnic initiator controller (PIC) which governs the pyrotechnic circuits
on the Shuttle. The problem was narrowed down to a prematurely charged
capacitor in the firing circuit of all eight Solid Rocket Booster hold down
posts and the T-0 liquid hydrogen vent arm, located on the side of the external
tank.  This charge is normally initiated at the T-18 second mark.


7/15/93:  DISCOVERY READY TO LAUNCH ON MISSION STS-51

KSC Release No. 85 - 93

     The Space Shuttle Discovery is prepared and ready to launch on its 17th
voyage into space.  Launch remains scheduled for the opening of a 62-minute
window at 9:22 a.m.  EDT from Kennedy Space Center's Pad 39-B.

     Preparations for Discovery's flight began just hours after the orbiter
returned from its most recent mission, STS-56, launched on April 8, 1993.
Discovery landed at KSC's Shuttle Landing Facility (SLF) on April 17 and was
towed a few hours later to Orbiter Processing Facility (OPF) bay 3.  In the OPF
the vehicle underwent standard turn-around operations and was prepared for
transfer to the Vehicle Assembly Building (VAB) on June 18.

     Once in the VAB, Discovery was mated to the external tank (ET) and twin
Solid Rocket Boosters (SRB).  Following standard Shuttle interface testing in
the VAB, the entire Shuttle vehicle was rolled out to pad 39-B on June 26.  The
day before rollout, the primary payload, the Advanced Communications Technology
Satellite/Transfer Orbit Stage (ACTS/TOS), was delivered to the pad's payload
changeout room.  The next day Discovery's payload bay doors were opened and the
ACTS/TOS payload was transferred to the orbiter's payload bay.

     Pad 39-B was turned-around in just 4 1/2 days from the time Endeavour was
launched on June 21 and Discovery was rolled out on June 26.

     On June 30 the final phase of the Terminal Countdown Demonstration Test
(TCDT) was conducted.  The test involved the KSC launch team as well as the
five crew members of mission STS-51. During the TCDT, STS-51 Commander Frank
Culbertson made an orbiter-to-orbiter communications check with STS-57
Commander Ron Grabe, who had just landed the Shuttle Endeavour at KSC's SLF.


     At the pad, Discovery underwent typical pre-launch preparations and the
countdown to launch the fifth Space Shuttle mission of the year began on time
at the T-43 hour mark at 9:30 a.m., July 14.

     Mission STS-51 is scheduled to last nine days.  An additional day on orbit
may be permitted if enough onboard cryogenic reactants are available.  Landing
is scheduled to take place at KSC.

     The crew for mission STS-51 are: Commander Frank Culbertson, Pilot William
Readdy, and Mission Specialists Daniel Bursch, James Newman and Carl Walz.
